GER and respiratory symptoms are both common phenomenon in children. Both can coexist in the same patient by chance alone. Research reveals increased incidence for both to coexist leading to suspect a temporal association and possible causality. Therefore we conducted an observational study To determine the primary cause (RS or GER)using for the first time both PH-Impedance as measurements of GER and Wheezy monitoring (WEEM) that records simultaneously wheeze and cough noises. Both modalities will be recorded for 12-24 hours. If GER precedes cough/wheeze recordings it points to GER being the possible precipitating factor and vice versa.

loudspeaker recording (WEEM) is attached externally to the chest simultaneously with PH-Impedance.

B

Children 2-18 years old

Device: WEEM - Wheezy Monitoring

loudspeaker recording (WEEM) is attached externally to the chest simultaneously with PH-Impedance.

Detailed Description:

GER and respiratory symptoms are both common phenomenon in children. Both can coexist in the same patient by chance alone. Research reveals increased incidence for both to coexist leading to suspect a temporal association and possible causality. Therefore we conducted an observational study To determine the primary cause (RS or GER)using for the first time both PH-Impedance as measurements of GER and Wheezy monitoring (WEEM) that records simultaneously wheeze and cough noises. Both modalities will be recorded for 12-24 hours. If GER precedes cough/wheeze recordings it points to GER being the possible precipitating factor.However, If cough/wheeze precedes GER recordings it points to cough/wheeze being the possible precipitating factor. The recordings will be investigated 1 minute before and one minute after each event.

Probability Sample

Study Population

We studied 23 consecutive Difficult to treat infants and children suspected of suffering from both RS and GER with chronic respiratory symptoms. However, four dropted due to technical problems wiht the equipment. In 19 patients We fully analyzed the respiratory sounds one minute during and one minute before and one minute after each GER episode, and in all parental markings of cough.
